I used to chart everyday. Wake up and take my temp before moving, stare at toilet paper deciding how stretchy, how egg whitish, mark my cramping, my moodiness... I did this for over a year, making sure I was ovulating and that we were timing right. This got old quickly. I am sure anyone else you has charted for long periods of time would agree. It also became very stressful. Not forgetting, staring at graphs and finding patterns, making sure M and I were in the right mood at the right time. I became so focused on the charting; it was crazy! So I decided I had gleaned all I could from that awful ritual. I stopped. I haven't charted in over a year and I have not looked back. I understand that it can be a helpful tool in establishing patterns, tracking ovulation, and diagnosing a problem, but charting is not for me. Fortunately I have a pretty consistent routine going on, but I have stopped even keeping track of ovulation. There are signs I pick up on and then think, "is it already ovulation/period time again?" but I have found life to be much more enjoyable the less I focus on my cycle. Less stress, less depression and less tension (and better sex). And I don't think that not charting has affected us. Yes we don't have a kid, but I doubt charting would have changed that.
My advice: Don't let charting rule your life!
